scrollTo() causes a full freeze of thread

[GoogleCodeExporter]

What steps will reproduce the problem?
Use a scrollTo() as part of a ViewAction in a perform() method.

What is the expected output? What do you see instead?
I would expect the execution to move onto the next ViewAction, but instead it 
locks up, and the thread continually waits.

What version of the product are you using? On what operating system?
Running on Nexus 4, 4.3 JellyBean

Please provide any additional information below.

The view *is* in the layout, and is a descendant of a ScrollView. There is 
nothing special about the layout. The text is non-null. The view is View.VISIBLE

Sample line causing issues: 
onView(ViewMatchers.withId(R.id.prescription_remarks_edit)).perform(ViewActions.
scrollTo(), ViewActions.typeText(mMedication.getRemarks()));

It'll be very difficult to debug this without a repro that we can run locally. 
If you can't share the exact activity on which this happens, could you put 
together a repro with a similar test activity and attach it to the bug?

+ please add a full thread dump. Just the instrumentaiton thread is not 
interesting.

No additional info provided, so resolving "won't fix".

I also faced the similar issue when i was using the Junit3 framework for 
testing my application,In which i used the Solo.ScrollToTop() for going to the 
top of the screen. I think it is avery critical issue and needed to be 
fixed.Here is state of my InstrumentationRunner once it stops running without 
any error or crash (i found it going to indefinite waiting state)
